The present-- invention relates to sounding devices or leads for ascertaining the depths and conditions of the bedsw-of oceans and other water-ways,and -for collectingspecimens and sainples'thereof. The obj ect of the invention includes mean in the form of a scoop or cup movably mounted in the'base of the lead and acting upon contact with the water-bed to collect and hold relativelysoft orloo se particleser samples of which the bed may be formed. A further object is to provide resilient means normally acting to effect a joint collecting and closing movement of the cup.

1 Also, to provide a detent adapted to hold the cup in open position in opposition to said resilientmeans, and to provide tripping means for said detent operable upon contact with the water-bed.

Also, to provide an arrangement whereby the working parts are essentially disposedwithin the body of the lead and protected thereby against injury.

For further comprehension of the invention, and of the objects and advantagesthereof, reference is had to the following description and accompanying drawing, and to the appended claims in which the various fea tures of the invention are more particularly pointed out.

Referring to the drawing in which similar characters of reference designate like parts throughout the several views: 2

Figure 1 of the drawing is a side eleva- .tional view of a sounding leadembodying my invention. 7

Figure 2 is an elevation a]. viewshowiug the base portion of the lead takenat right angles to .F 1. r I

Figure 3 is an elevational view of the base portion of the lead with the cover-plate removed to show the operating parts.

, Figure 4 is a sectional elevation of the base taken on the line 4=-4 of Fig. '5.

Figure 5- is a transverse sectional'viewof the base portion of the lead taken on the line 5-5 of Fig. 4.

Numeral 10 of the drawing illustrates the lead or weight connectedto the sounding-line 5 11, the base or bottom face of the lead being provided, as herein shown with a semispherical recess12. In the opposite side walis of the latter is rotatively mounted a spindle 18, having fixed at one end thereof a swi1 1g mg lever-arm 14, and at its opposite end a rand-grip 15, by means of which the spindle may be turned a portion of arevolution.

Upon the spindle is fixedly mounted a semispherical closure cup 16 adapted to freely turn within the recess'12'of the lead, the inner edges of the cup being beveled as at 17 for a portion of its distance around to serve as a cutting or scooping edge, the remaining portion forn'iing a squared edge at 18, adapted to seat'against the inneredge of the packing- (5 ring 19 when the cup is in open position. The inner face of the packing-ring is shaped to slidingly engage the outer surface of the cup during its part rotation and effect a substantially close joint therebetween, a seat being also providedalong the bottom edge of the packin -ringat 20 to effecta close joint when the cup is in closed position, as shown in the dotted lines 21 in Fig. 4.

For'operating the cup a side recess 22 is 3'" formed in the base of the lead and adapted to be closed by the cover-plate 23 and form a chamber to receive the swinging lever-arm 14:; Aspring 24 isalso positioned Within the side recess or c'hamber22, one end of the U lead base by the pin 26. The tension of the spring in its straight-line position belowthe axis of the spindle 13, as shown in Fig. 3, g;

serves to urge andhold the cup in open'position against the inner edge of the packingring 19, indicated at 18 in Fig. 1. The cup is also held normally in open position by a trip-rod 27, endwise slidable within the base of the lead and is provided with a projecting stop-pin 28 that extends into the recessed chamber 22 and is adapted'to freely engage the lower edge of thearm 14 while the cup is" closed; Inthis latter position. of thecup '35 the trip-rod projects'below the bottom face ofthe lead and is adapted during the sound ing operation to engage the water-bed, where= by-the weight of the lead forces the tripfrod 27-to move inwardly thereof, causing the stop-pin 28 to upwardly force the arm it against the downwardly closing action of the spring 2 1, the upward. movement oi the arm serving to raise the straight-line action of the spring above the axial center of the spindie and in which position it is free to act and resiliently eilect the closing movement of the cup.

In the closing movement of the cup its beveled edge acts to cut away, scoop up and securely enclose relative loose substances with which it engages, and by the resilient movement in which the work is accomplished substantially no time is allowed for the lead to turn about its base and interfere with the desire result tohe obtained.

In the closed position of the cup as shown in full lines in Figs. 1 and and in dotted lines in Fig. 4, the cup arm 14, shown in full lines in Fig. 3, assumes the dotted-line position 14" and the position of the connected spring the dotted line position 24:.

It is to be understood that detail changes in the structure ot' the device may be ma de withoutdeparting from the scope of the present invention.

Vhat I claim as my invention and desire to secure by Letters-Patent, is z 1. A sounding lead having in its bottom face a recess, a closure cup mounted to turn within said recess and provided with a beveled-closing edge, resilient'means normally acting toclose said cup, means arranged to hold said cup in open position in opposition to said resilient means, and a trip-rod adapted to release said resilient means and close said cup.

2.- A'sounding lead having in its bottom face a recess, aspindle mounted to turn in the opposite side walls ot'said recess, a closure cup fixed to said spindle within said recess, resilient means normally acting through said spindle to close said cup, means arranged to holdsaid cup in open position in opposition to' said resilient means, and a trip-rod adapted to release said resilient means and close said cup.

A sounding lead having in its bottom face a recess, a spindle mounted to turn in theopposite side walls of said recess, a 010- sure cup fixed to said spindle within said recess, an arm for rotatingfsaid spindle, resilientnieans normally adapted to rotate said spindle through said man and close said cup,

and means for rotatingsaid spindle in. opposition'to said resilient means and opening said cup. V V

4. A sounding lead having in its bottom face a recess, a spindle mounted to turn in the opposite side walls of said'recess, a closure cup, fixed to said spindle within said recess, an arm for rotating said spindle, resilient means connected to said arm and normally adapted to rotate said spindle and closejs aid cup, means for rotating said spindle in op position to said resilient means for opening said cup, a chamber formed in a side wall of said lead and disposed to receive said operating arm and resilient connections, and acoverplate for said chamber.

- 5. In a sounding lead having in its bottom face a recess, a'closure cup mounted to turn within said recess, resilient means normally acting to close said cup, means arranged to open said cup in opposition to said resilient closing means, and packing disposed within said recess and adapted to seal said cup in its open and closed positions with respect to said recess.

6. In a sounding lead having in its bottom face a semi-spherical recess, a semi-spherical closure cup mounted to turn within said recess, resilientmeans normally acting-to close said cup, means arranged to hold said cup in open position in opposition to said resilient means, and a trip-rod adapted to release said resilient means and close said cup.
